[help] binary Matlab

[Permenkaret]

gan ane bkin program konversi biner to ASCII pake MATLAB... gini gan:



misal binernya : x = 011111010110001011000001101000010100



ane jadiin ASCII pake script ini


Quote:







t=length(x);

A=x;

[l m]=size(A);

for i=1:m

Data(:,i)=str2num(A(i));

end

hc=Data;



na='hasil.txt';

hasil=fopen(na,'w+');



for i=1:8:t

ck=t-i+1;

if(ck>8)

tp=(hc(i:i+7));

num=8;

else

tp=(hc(i:t));

num=ck;

end

temp1=b2d(tp,num);

temp2=char(temp1);

fprintf(hasil,'%c',temp2);

end

fclose(hasil);





ini file b2d.m


Quote:





function PW=b2d(tp,num)

PW=0;

j=0;

for i=num:-1:1

PW=PW+pow2(tp(i),j);

j=j+1;

end

return





ini hasilnya gan : }ba



nah ane balikin lagi ke biner




Quote:





nme='hasil.txt';

id = fopen(nme,'r');

a = fscanf(id,'%c',inf);

fclose(id);



[m,n]=size(a);

k=1;

for i=1:n

b(i)=double(a(i));

end



for i=1:n

c = dec2bin(b(i),8);

for j=1:8

d(k)=c(j);

k=k+1;

end

end

disp(d)





hasilnya : 0111110101100010110000011010000100000100



kelebihan 0 sebanyak 4... ada yg bisa gak cara ngatasinya... please!!!
